This invention relates to submarine drills,

but more particularly to. the type of submarine hammer drill unitdisclosed "in United States Patent llor1 ,610,372, granted PC I drillunit as will serve to illustrate the in- December 14, 1926.

The objectof the presen't' invention is to enable the drill steel to beguided by means of a'suitable d rill steel guide which is moved'upanddown the guide frame of theunit as the drilling apparatus ismoved.

By this means the drill steel guide is automatically adjustedto guidethe steel in any position, as for instance, when changing steels orwhenlowering' the drilling: apparatus to insert the steel in thesubmerged mud guard.

The necessaryop'erations of. submarine dri11'-,

ing with a hammer'drill and short orlong steels are: thus: facilitated?and, the; time consumed in making adjustments considerably lessened;

The invention is shown in one of: its; preferred forms inthe:accompanying drawings,

in which I Figure l is an end elevation, partly in vertical section andpartly broken away,

showing so much of a barge and submarine V vention,

Figure 2 is an enlarged detail view, partly broken away and partly invertical section, of the lower portion of the drilling unit and thedrill steel guide,

Figure 3 is'a transverse sectional Figure 2 taken on the line 33 lookingin the direction of the arrows, and

Figure 4C is a side elevation, partly broken away, showing two drillingunits on a barge.

Referring to the drawings, a barge A is shown broken away and in thisinstance two submarine drilling units B having a main frame C areillustrated on the barge. A

submarine hammer drill D'for each unit channels H and the drilling frameE is guided on said guides G. The main frame is also provided withbrackets J and a supplemental guide frame formed of the'rods K connectedby the foot piece L is slidable in a the brackets J.

view of V drill steel P carried by the rock drill D ex tendsthrough the-mud guard during the drilling; operation. A suitable motor Q, havingthe winding drum R carries the cable S for raising and, lowering theguide frameK and other motor'T may be provided for op-f erating thecable U for raising and lowering the: drilling frame E.

In accordance with thisinvention, a drill 1 steel guide V in the form ofa plate is freely the rock to be drilled: and the short hollow Islidable vertically 0312 the rods K forming the guide frame and in orderthat this drill steel guide; may guide the steel? both during thedrilling operation and when steels are to becha-nged, suitable means areprovided for raising andlowering; the drill fsteel.

ible looped connections Z are secured to the main cables WV at a and arealso secured to the drilling frame E at the point I). By thisarrangement, as the drilling frame E is raised, theloops Z are drawntaut and raise the drill steel guide V upwardly. The counterweights Ykeep the main flexible connections and the loop connections taut andtake up slackwhen necessary.- The drill steel guide V may also bemanipulated from] the barge by means of the flexible connections W. I vI claim:

r 1. A submarine drill unit, having a main frame provided with guides, aguide frame vertically movable on said guides, a drilling element, atubular 'mud guard adjustably supported at the lower end of said guideframe below the drilling element whereby the weight of the drillingelement may rest upon the mud guard to force it down to the rock to bedrilled, a'drill steel guide freely slidable vertically on t-he'guideframe, and means forraising and lowering said drill steel guide.

2. A submarine, drill unit, having a main frame provided with guides,-aguide frame vertically movable on said guides, a drilling element, atubular mud guard adjustably supported at thev lower end of said guideframe below the drilling element whereby the weight of the drillingelement may rest upon the mud guard to force it down to the rock to bedrilled, a drill steel guide ad- I justable vertically with respect tothe guide frame, and aflexible connection between said drill steel guideand the drilling element.

3. A submarine drill unit, having-amain frame provided with guides, aguide frame vertically movable on said guides, a drilling element, atubular-mud [guard adjustably supported at the lower end of said guideframe below the drilling element whereby the weight of the drillingelement may rest upon the mud guard to force it down to the rock to bedrilled, a drill steel guide adjustable vertically with respect to theguide frame, main flexible connections secured to' the drill steel guideand extending to points 7 on the main frame, and flexible looped eonuponthe mud guard to force it down to the nections between said mainconnections and the drilling element, whereby the raising ofthe'drilling element also lifts the drill steel guide. 7 V r I 4.
